Dreams are basically simulations of our lives that we run, sometimes with different physical constants, resulting in different worldly behaviours. Fever dreams (not necessarily during a fever) are when we are sweeping over a range of constants, so behaviour keeps on changing.
Or, am I really the butterfly and this is the simulation?

i dont really have anything to add or ask, but appreciate what seems like unicode character in your username.
